Direct-Fired Thermal Oxidation – DFTO

If you need to remove high concentrations of harmful substances from your process exhaust gases safely and efficiently, our Direct-Fired Thermal Oxidation (DFTO) solution is an ideal choice. The system is designed to eliminate volatile organic compounds (VOCs) effectively even at very high and potentially explosive concentrations.

How direct-fired thermal oxidation works:

Exhaust gas with a high pollutant concentration is fed directly into the oxidation chamber. A high temperature is maintained in the chamber and, together with an optimally selected residence time, ensures complete oxidation of hazardous substances. These are converted into harmless products such as water vapour and carbon dioxide. The process ensures that even exhaust gases with a high explosion risk can be cleaned safely and efficiently.

Key benefits of our DFTO system:

  • High VOC removal efficiency: Eliminates more than 99% of harmful emissions from exhaust gases.
  • Treatment of high concentrations: Safely destroys even very high and potentially explosive pollutant concentrations.

Our DFTO system is ideal for:

  • Small air volumes: Optimized for processes with smaller exhaust-gas volumes.
  • A broad range of pollutants: Suitable for different harmful substances in exhaust gases.
  • High pollutant concentrations: Effective even at very high VOC concentrations.

What is direct-fired thermal oxidation, and how does it work?

Direct-Fired Thermal Oxidation (DFTO) is a process in which exhaust gases with high concentrations of volatile organic compounds (VOCs) are combusted directly in an oxidation chamber. The high temperature and optimal residence time ensure that harmful substances are converted into harmless water vapour and carbon dioxide.

Which applications are best suited to a DFTO system?

DFTO is ideal for industrial processes with small exhaust-air volumes but high VOC concentrations. It can also handle a broad range of pollutants, making it a versatile solution for many types of operation.

What advantages does DFTO offer over other exhaust-gas treatment methods?

DFTO’s principal advantage is its ability to treat high and potentially explosive VOC concentrations safely, with an efficiency of over 99%. Direct combustion also makes the system simpler and potentially less maintenance-intensive than systems using heat exchangers or catalysts.

How does a DFTO system affect operating costs?

When high VOC concentrations are treated, the energy content of the pollutants themselves can support the combustion process and reduce fuel consumption. However, because the system must maintain a high temperature in the oxidation chamber, operating costs may be higher than for heat-recovery systems.

How does DFTO help protect the environment?

By eliminating more than 99% of VOCs from exhaust gases and converting them into harmless substances, DFTO reduces harmful emissions into the atmosphere. This helps operators meet stringent emission limits and protect the environment.
